Objective: Psoriasis is a chronic, papulo-squamous skin disease characterized by circumscribed, erythematous, scaling, thickened plaques. The primary cause of psoriasis is unknown; however recent genetic and immunological researches have increased understanding of the pathogenesis of psoriasis as a chronic, immune mediated, inflammatory disorder. Some research groups have implicated CD8+ T cells as predominant in psoriatic epidermis and find that reduction in this subset during treatment of psoriasis correlates most closely with disease resolution. Many studies have been published about hearing in autoimmune diseases, however studies about hearing loss in psoriasis have been very limited. The aim of this study was to investigate cochlear functions and hearing evaluation in patients with psoriasis.
